Taken from the header file:
* All settings max_freq and min_freq are in terms of radians per sample,
* NOT HERTZ.  Alpha is the phase gain (first order, units of radians
per radian)
* and beta is the frequency gain (second order, units of radians per
sample per radian)

For a good theoretical and practical description of the parameters
